The Linearity Figure of Merit (LFoM) is a quantitative measure used to evaluate how closely a system's response aligns with a linear model, often crucial in assessing the performance of sensors and measurement instruments. It provides a single value that encapsulates deviations from linearity, aiding in the comparison and optimization of devices for precision and accuracy in various applications.

A quantitative measure is a numerical representation of a property or characteristic, allowing for objective analysis and comparison. It is fundamental in fields like science, economics, and engineering for making data-driven decisions and validating hypotheses.

A linear model is a mathematical representation that assumes a linear relationship between input variables and the output variable, often used for prediction and analysis in statistics and machine learning. It is characterized by its simplicity and interpretability, making it a foundational tool for understanding more complex models.

Precision refers to the consistency or repeatability of measurements, while accuracy indicates how close a measurement is to the true or accepted value. Both are crucial in scientific and engineering contexts, but a measurement system can be precise without being accurate and vice versa.
